Introduction
The I/O board handles the connectors for the SD card slot, headphone jack, reset button, and the power button.
Use this guide to replace a faulty or failing I/O board in your Lenovo IdeaPad 3-1481W000NGUS.
The I/O board handles the connections for the SD card and headphone jack. Internally, it also handles the reset button and power button. If SD cards are unable to be read, the audio connection is crackly or quiet, or if the computer cannot be reset or turned on, the I/O board may be at fault.
Before using this guide, make sure to review the [[Lenovo IdeaPad 3-1481W000NGUS Troubleshooting|troubleshooting page|new_window=true]]. Oftentimes, audio and connection issues can be fixed without replacing the I/O board.
Never work on an electronic device that is plugged into a power outlet. Before starting this guide, ensure that the laptop is fully powered off and that the power adapter is disconnected. Follow the steps in order as the battery must be disconnected before removing other connectors.
